Hello there,
In my current project, I have a similar need to detect if a variable
is a jQuery object or not.
I finaly decided to add a $.isJQuery() method to jQuery namespace that
could acts like a regular $.isArray or $.isFunction.
Not sure, this is the best way to do this but I used something like:
$.isJQuery = function(o){
try {
// no matter the checked method, just ensure calling it not
raise an error
o.is();
return true;
}
catch (e) {
return false;
}
};
That did the trick for me.
Best regards,
